Shows OpenPOWER in Libre-SOC

The chip made on the TSMC’s 180 nm node can be found in smaller embedded systems.

IBM announced in 2013 that the Power architecture could be licensed, and then in 2019, the OpenPOWER Foundation merged into the Linux Foundation, and in parallel, Power ISA (instruction architecture) became open source. The latter factors were needed for the birth of the Libre-SOC project, which aims to design an open source chip that can be deployed in embedded systems that build on open source software.

Libre-SOC is special in that it is the first development to use Power ISA independently of IBM, and every element of the chip is open source, so anyone can upgrade, although this is obviously more difficult for a piece of hardware. way as with software.

Libre-SOC itself will be built on TSMC’s 180 nm node and will use a processor core compliant with OpenPOWER ISA v3.0B, in the company of a custom-designed integrated graphics controller and integrated video processor. Thanks to the latter two components, the handling of the Vulkan API and more modern codecs has also been solved.

This combination allows for low-cost embedded systems, as well as an open source operating system and driver support.

It is important to know about the current prototype that it can best be interpreted as a zero generation product, its essential purpose is to put it on the map. This is likely to be the case, as it provides a good foundation for implementing software improvements, but more powerful variants will come in the longer term. Based on current designs, four- and eight-core system chips will be created, in addition to the SVP64 instruction set, which will be used to insert vector engines into the chip. These are expected to be completed in two to three years, and more cores will be installed later.
